• Once the calibration is complete, your pH Perfect is ready to regulate your
pool automatically.
• If your water chemistry is badly out of balance please bring your pool pH
within balance before activating the pH Perfect.
The pH Perfect peristaltic pump is self-starting. However, it is possible to operate it manually by
keeping the ”
p
“ Navigation button pressed.
The peristaltic pump will then inject corrective solution as long as the button is pressed.
3.2 Rule for injecting pH Perfect
Proportional cyclic dosing - exclusive to Zodiac
•
To reach the set point in the best possible conditions (the quickest, but with the least possible
corrective solution), your pH Perfect automatically detects the difference of the pH value measured
in the pool compared with the desired set point (default value = 7.4 pH).
•
This proportional injection is cyclic and the cycle time is 10 minutes. What will change in dosing is the
different times of injection and pause. The proportions are adjusted automatically and the different
dosages are distributed in steps of 0.15 pH.
E.g.: For 4 cycles with a set point of 7.4 pH and acid regulation (standard alkalinity levels)
:
pH
≥
7,55
: 20% injection (2 minutes) & 80% pause (8 minutes)
pH
≥
7,70
: 50% injection (5 minutes) & 50% pause (5 minutes)
pH
≥
7,85
: 75% injection (7 minutes 30 seconds) & 25% pause (2 minutes 30 seconds)
pH
<
7,90
: 100% injection (10 minutes, continuous)
